Electronics Polypro Membrane Capsules - 1

EPM Capsule Filters Polypropylene Membrane Applications Etchants Tank Vents Acids & Bases Process Gases Solvent Filtration Non-aqueous Solutions Electronics grade EPM capsules are made of materials specifically chosen for their compatibility with chemicals and solvents. They have minimal extractables when exposed to those chemicals and solvents. Each capsule module is flushed until the rinse effluent reaches 18+ Megohm-cm and less than 3 ppb TOC. Each cartridge module is also individually tested to ensure integrity. Optimized for maximum filter life Designed for sterilizing filtration of air and process gases F inal filtration of solvents, alcohols and other nonaqueous liquids The capsule media surface area, filter core design, pleat configuration and pleat packing density are all optimized to provide increased life. Capsule Length Polypropylene Membrane Flow Rate / Filtration Area The following table represents typical water and air flow at a one psi (69 mbar) pressure differential across a single 2 inch capsule with 1.0 ft ² (930 cm²) of media with 1/2” FNPT ports. The liquid test fluid is water at ambient temperature. The gas test fluid is compressed air at ambient temperature. Higher pressure drops are acceptable, but as flows increase the pressure drop of the housing becomes more apparent.
